In this image provided by NASA Thursday June 16, 2011 the crater Degas was obtained as a high-resolution targeted observation (90 m/pixel). The image shows the impact melt coating the floor of the crater, and as the melt cooled and shrank, it formed the cracks observed across the crater according to scientists. After nearly three months in orbit about Mercury, MESSENGER's payload is providing a wealth of new information about the planet closest to the Sun, as well as a few surprises. Tens of thousands of images of major features on the planet — previously seen only at comparatively low resolution — are now available in sharp focus. (AP Photo/NASA) less
